DAVID Cameron has admitted that he misses wife Samantha 'desperately' when he travels around the world without her on official business.

The Prime Minister, speaking to schoolchildren during a question and answer session in Kazakhstan, opened up about missing his wife on long business trips.

Mr Cameron has been overseas since Thursday on a visit taking in the European Council in Brussels, Afghanistan, Pakistan and Kazakhstan.

He said: "I do still remember vividly the day I was married. It's the most exciting day of your life. I still remember it.

"I haven't seen my wife for several days now and I miss her desperately."

While speaking Mr Cameron also admitted he would like to be boy wizard Harry Potter but said the British public would probably view him as Voldemort.

Asked which character in the JK Rowling books he would like to be, he said: "My daughter is nine years old, she's just started to read all the Harry Potter books so I'm sort of rediscovering them all over again.

"I can think of all sorts of characters you don't want to be and I suppose in the end you know if you've got any sense you want to be Harry Potter. That must be the correct answer.

"But I suspect people in Britain might want to paint me in a different role but I'll let them do that, I won't make the work easier for them."

Asked about his student days reading politics, philosophy and economics at Oxford, Mr Cameron said: "I was very lucky to have some very good tutors.

"In fact some of them still write me letters, often telling me that what I am doing is not a good idea but every now and again saying well done.

"They keep in touch, I think they still feel they are training me even now."

Mr Cameron was presented with a Nazarbayev University hoodie and cap on his visit.
